About

Chapter One

2014 to 2023

Hi, I'm Gökhan and here's my story in a nutshell:

Founded Trifles Games and scaled it to $1M+ revenue from the ground up (Forbes verified).
Built and managed a 29 person full time team on site.
Featured on Forbes Europe 30 Under 30 at age 27 (2023).
Won 2nd place in a national TV game development competition in 2019 with a multiplayer shooter.

I studied software development in high school and computer science at Bursa Uludağ University. I have worked with Unity since version 3.5.7 and started freelancing in 2016.

Chapter Two

2024 to now

In early 2024 I moved to Estonia with my wife.

Most recently I built RedSim, a global eSIM app, completely solo, from the Flutter frontend to the entire backend, payments, and provisioning. It's live in the App Store, supports 18 languages and 200+ countries.

These days I build apps with Flutter and AI across the workflow, and share what I learn as I go.

Chapter One · Trifles Games · 2014 to 2023

A studio in the heart of Istanbul.

I built Trifles Games from the ground up. Set up an office in Istanbul, grew the team from 0 to 29 people, shipped dozens of mobile games and partnered with publishers like Rollic and Homa Games.

We also self published our own games and ran serious user acquisition on them, including $250K+ in ad spend on Fashion Challenge alone.

Chapter Two · 2024 to Now

We packed up Istanbul and moved to Tallinn.

New chapter · New country · New life

In 2024, my wife and I left Istanbul and moved to Estonia. Building a profitable company in Turkey was doable. Raising from serious investors and operating in a stable currency was not.

Tallinn put us inside the European startup ecosystem, closer to the funds, founders and markets we wanted to build for, without the dollar crisis and quarterly tax fights in the background.

Two years in, Tallinn feels like home. We are happy here, building a life together and finally working on the ideas we always wanted to chase.

Launched June 2026

RedSim. Built solo.

A global eSIM app for travelers.

Travel data is still a mess. Roaming bills, slow airport SIM cards, clunky apps. Once we started traveling more from Tallinn, I kept hitting these problems myself and saw a real product gap.

eSIM was the right category. Clear pain point, global audience, and a product I could grow on my own through UGC, affiliates and paid ads.

I built the whole thing end to end. Flutter app, backend, payments, eSIM provisioning, support and growth. No co founder, no team, no agency. Today it is live in the App Store, working in 200+ countries and 18 languages.

Airalo basically created this category. Instead of competing head on, we work with them and a few other providers. The goal is to grow the eSIM space together and get more travelers off roaming.
